SmartCrop: You have provided a FaceIndex value that exceeds the length of the zero-based detectedFaces array.

I’m attempting to use the smartCrop option:

edits: {
  smartCrop : true
}

This error is logged in CloudWatch:

{ status: 400,
code: 'SmartCrop::FaceIndexOutOfRange',
message: 'You have provided a FaceIndex value that exceeds the length of the zero-based detectedFaces array. Please specify a value that is in-range.' }

It is failing because of this line. It doesn’t first check if any faces were detected before it starts defining the bounding box. In my opinion, smartCrop should fail gracefully (not crop) if no faces were detected in the image. Would you accept a PR for this, or provide some advisement on how best to implement it?

I upgraded to v5.2.0. It returns a 400 error with these settings:

smartCrop: {
  faceIndex: 0,
  padding: 1
}

{“status”:400,“code”:“SmartCrop::PaddingOutOfBounds”,“message”:“The padding value you provided exceeds the boundaries of the original image. Please try choosing a smaller value or applying padding via Sharp for greater specificity.”}

No matter what padding value I try it returns the same error. If no padding is passed it does return a face very closely cropped and not really usable.

can we expect this to be fixed in the next release, waiting for this since July. Also I hope the images will be cached after processing as calls to rekognition are chargeable.
